A cylinder with a mass M and radius r is floating in a pool of liquid. The cylinder is weighted on one end so that the axis of t

he cylinder stands vertically. The total length of the cylinder is L. The density of the fluid is rho.
a. When the cylinder is in equilibrium, a portion of it is submerged in the liquid. What is the vertical length h of this submerged portion? Your answer should use only the given symbols M, r, L, and rho as necessary, as well as the constant g.
b. The cylinder is now displaced a distance y from the equilibrium position, such that |y| < h, and released from rest. Let the +y-axis be upward, so that if the cylinder is pulled up, y is positive, but if it is pushed down, y is negative. Immediately after it is released, what is the y-component of the acceleration ay of the cylinder? Your answer should use only the given symbols M, r, L, y, and rho as necessary, as well as the constant g.
c. The result of part (b) implies the cylinder is now in simple harmonic motion. What is the period T of the cylinder's oscillations

if charge is located at center of spherical volume and electric flux through surface of sphere is Φ what would be flux through s
jonny [76]

Answer:

The flux will be nine times as great.

Explanation:

The electric flux due to a charge Q located in the center of a sphere can be obtained using Gauss's law. Considering a Gaussian surface in the form of a sphere of radius r:

\Phi_E=\int\limits {Ecos\theta dS} \,

The electric field (E) is parallel to the surface vector (dS), so \theta=0

\Phi_E=\int\limits{Ecos(0)dS} \,\\\Phi_E=E\int\limits{dS} \,\\\Phi_E=ES\\\Phi_E=E4\pi r^2

Since the electric flux is proportional to the square of the sphere's radius,  if radius of sphere were tripled, the flux will be nine times as great.

Rita places a 2.5 kg block on a frictionless inclined plane that is 30 degrees above horizontal. She applies a horizontal force,
vitfil [10]

Answer:

14.2

Explanation:

find horizontal force of the weight = 2.5kg x 9.8 Sin30 = 12.3 N

to prevent the sliding she needs to pull horizontally

Fh = 12.3 /Cos 30 =14.2N

A surface completely surrounds a 3.3 × 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphe
KengaRu [80]

Answer:

Electric flux in a) , b) and c) is same which is   0.373 × 10 ⁶ N m²/C

Explanation:

given,

surface charge (q) = 3.3 × 10⁻⁶ C

to calculate electric flux = ?

a) radius = 0.76 m

area of sphere = 4 π r²

electric flux = \dfrac{q}{\varepsilon}

\varepsilon = 8.85 \times 10^{-12} C^2/Nm^2

electric flux =  \dfrac{3.3 \times 10^{-6}}{8.85 \times 10^{-12} }

flux = 0.373 × 10 ⁶ N m²/C

electric flux in the other two cases will also be same as electric flux is independent of area

so, Electric flux in a) , b) and c) is same which is   0.373 × 10 ⁶ N m²/C

A machine lifts a 44,760 newton crate 2 meters into the air in 10 seconds. How many horsepower does the machine
VladimirAG [237]

Answer:

<u>8952 W</u>

Explanation:

<u>Given</u> :

  • Force = 44,760 Newtons
  • Displacement = 2 meters
  • Time taken = 10 seconds

<u>Equation</u>

  • Power = Work / Time
  • Power = Force x Displacement / Time

<u>Solving</u> :

  • P = 44760 x 2 / 10
  • P = 4476 x 2
  • P = <u>8952 W</u>
